heh idk exactly what happened. i was 3/4 throttle up till third gear and i started to roll on the throttle a bit harder. the turbo somehow huffed and puffed to 12 lbs. i saw that spike on my gauge and let off but i guess it was too late! after that there was just a lot of smoke

looks like it snapped the turbo shaft and it rattled around a little.

I did that (less damage) on my celica.

broke.

Looks like it overspun. I don't get the 12psi spike though. Oh well, it's some good carnage.

You are damn lucky that happened on the exhaust side and not on the intake side. Serious carnage. :(

Just a theory... wastegate dies, malfunctions, whatever. Turbo spins way up. Boost rises but you are past compressor efficency so it's just a race to see what dies first, turbo or engine. You got lucky and it was the turbo.

maybe it was a single turbo setup on a V8.

yeah well... the stock mazdaspeed turbo from what i hear can only spin up to about 12psi. sooo yeah... probably not getting warranty on it as when something breaks i see it as an opportunity to upgrade!

and yeah guess i didnt look hard enough for a saying hi thread. my bad i think its turning into more of a... "wow your turbo got pwned thread"

sure people may attempt to run more, and very well may... but not for long. that turbo is out of its efficency by 10lbs from what i understand. and are these people running the STOCK turbo, without the FM upgrade to the cold side? i believe the rule of thumb is 1-2lbs over max efficency and youre good, after that sh*t hits the fan, some what literally i suppose. and knowing plenty of people running more is somewhat of a bold statement considering there are only about 5000 msm in the US, and only a small percent of those are modded. i mean compared to the about 20k srt-4s out there... basically id like to know who is running more than 10? no one is without engine management.

few people on the www.mazda-speed.com/forum2 forums are running 12 or more on the stock turbo. owning my msm for over two years and being on the above mentioned forums for about 2 years, ive been watching the development of msm specific modification for awhile now. as most people know by now, mazdaspeed did a real crackjack job on the car. between the tiny turbo/injectors, lower than desired hp and crap ecu mapping the only thing that saves it is its increased handling capabilites and body stiffness. (not to mention the somewhat sexy racingharts, at least i love them)

i honestly have no idea what caused the turbo to blow. i really dont care either. im just going to replace it with a nicer garrett t25, get a hydra and move on. the car wont be fast, probably not ever. i dont have the time/money to invest in the internals to go 300+ hp. at least not now i think id rather have a vette before that day came anyway. from what i hear, the car seems to become far less balanced above 240hp. seems like 220 is really ideal for the car to stay really driveable and not over powering.

personally though, ill be making anywhere between that 240 and 275 whp, and it should be fun. the turbo i believe is 330hp capable but thats just silly to shoot for with my style of driving. rather have less power and have more fun with the car, longer.

sorry for the dely in my reply, im currently in australia on vacation. updates on my car will come few and far between unless i sell my motorcycle quick.

GO by what FM tells you, or go by what people on Mazda-speed tell you, but I laugh at you if you think all the modified MSM post there so what does it matter if tell you a lot you probably don't know them. How do you think this board was created, because Philip was tired of people saying you cant do this you cant do that on the net. You have a miata big deal, I'm on my second one, i've watch the development of the MSN, the BBK euro one, the Aussie SP. I've had a greddy modified one with prototype parts that are now sold, and I'm on my 2nd miata a Texas region equipped CS car. And I've been friends with some of the fastest and most powerful miatas in the last 5~6 years at one point or another. NOT everything everyone tells you on the net is truth. Not even some of the jokers @ other mazda sites

I really dont see a spike to 12 psi causing that damage. My TDo4H-15g spiked to higer than that several times, nothing happened. SO have turbos on other friends cars (non miata), including IHI turboed cars. The only cars I know that blow fins on spikes are those that have ceramic blades. It looks like something went through to me.

eh well think as you want man... never said all modified msm post there. youre the one to bring up the site remember? i simply pointed out that very very very few are running 12lbs and the likely hood you know a bunch of them is well... unlikely. its not like this is my first miata either. my family actually has 2 msm. this is my second miata. and if you think its fin damage that caused the turbine to snap off the shaft, i mean i suppose i could see how that could happen, but i figured it more likely that the shaft ceased. i think i may have been slightly oil starved. oil starve + boost spike cant be a good combo. but whatever, i really dont care what happened. it happened. i know the turbo can spool higher than 12. ive seen it up at 15 once in a blue moon, but i have no doubt the the high boost level contributed to the blow of the turbo.

and yeah, i will go by what many other people observe and test. i mean, because i really wanted to risk my turbo testing it before this happened. why would anyone want to risk their car when someone else is doing it?

and also, i hate how people try to compare other turbod cars to other ones, even if it is the same company manufacturing the turbo. who says that every ihi or garrett is going to behave the same way. especially when we're talking about a crappy stock turbo made for some what mass production.

there have been many discussions on the stock IHI turbo on mazda-speed.com. people calling ihi and all, i havent spent the time. if you really want me to to confirm what ive said i suppose i could just for you once i get back in the states.

whatever the case, its not about what you can or cant do, its about what you can get away with till it breaks. isnt that what most developing car forums are about?
